Title: Water stop plate
Inventor: WAKAMIYA MASATOSHI
IPC: C09K3/10
Filed: 1988-05-11
Abstract: PURPOSE:To always retain high water-stopping performance by forming a thick engaging portion at each of the lateral ends of a strip-shaped water stop plate and providing a water stop portion to the outside of the engaging portion. CONSTITUTION:A strip-shaped water stop plate 3, which is to be laid along a seam 2 between concrete structures 1, is formed of elastomer. A thick engaging portion 6 is then formed at or near each of the lateral ends of the strip- shaped water stop plate 3. A water stop portion 7 is also provided to the farther side of the engaging portion 6 on each side of said water stop plate 3. If a tensile force is exerted on the water stop plate 3 due to a slippage between the concrete structures 1, the tensile load is born by the engaging portion 6 with the result that the water-stopping performance of the water stop portion 7, which is located to the outside of the engaging portion 6, is hardly affected.

Title: Recording and reproducing method for synchronous signal
Inventor: MIYASHITA ATSUSHI
IPC: G11B20/10
Filed: 1988-05-11
Abstract: PURPOSE:To increase the detection accuracy of a synchronous signal by converting the bit weight of a word unit so as to contain a biased one in the word composing a synchronous pattern and setting the bit weight so as to be close to zero as the whole body of the synchronous pattern on those words. CONSTITUTION:The words used for a synchronous pattern contain those which bias the bit weight and are peculiar to other data patterns and in the whole body of the synchronous pattern, the 1st W in the synchronous pattern, for instance, is set like making a bit 0 numerous and the 2nd W making a bit 1 numerous in order to approach the bit weight to zero. Even if therefore the data string contg. the synchronous signal is recorded and reproduced by making it in series, the synchronous signal part is continued close to 7-8 pieces at its bit 0 and bit 1. It thus becomes a peculiar pattern to other data parts and the probability in error detection is reduced.

Title: Device for preventing image omission in transfer type electrophotographic apparatus
Inventor: TERADA RIYOUHEI
IPC: G03G15/02
Filed: 1979-09-03
Abstract: PURPOSE: To prevent image omission phenomenon in which a transfer paper waves in high humidity and floats up, hindering toner attachment, by controlling transfer charging voltage in inverse proportion to humidity.  
     CONSTITUTION: When a transfer paper absorbs moisture, it becomes soft, waves, and wrinkles, so part A floating up from a photosensitive drum occurs, resulting in causing image omission on image areas due to nontransferring of toner. At that time, the transfer paper is sufficiently extended laterally with guide 1a by lowering charging voltage of transfer charger 1 in order to weaken the close attaching force between the durm and the paper, and the floating part of paper A disappeares. Humidity rises in summer, and temperatures rises too, so the efficiency in charging and developing in an electrophotographic apparatus is enhanced, resulting in elevating image density too high. Therefore, the density is kept constant in high humidity by lowering the transfer charging voltage.
